Description of detection logic

IsRegressionBase: Marked as not a regression because the compare was not 5% greater than the baseline, or the value was too small.
IsImprovementBase: Marked as improvement because the compare was 5% less than the baseline, and the value was not too small.
IsImprovementCheck: Marked as improvement because the three check build points were 0.05 less than the baseline.
IsRegressionBase: Marked as not a regression because the compare was not 5% greater than the baseline, or the value was too small.
IsImprovementBase: Marked as improvement because the compare was 5% less than the baseline, and the value was not too small.
IsImprovementCheck: Marked as improvement because the three check build points were 0.05 less than the baseline.
IsImprovementWindowed: Marked as improvement because 192.82339007383098 < 224.86636585471425.
IsChangePoint: Marked as a change because one of 5/19/2023 4:22:12 AM, 9/23/2023 7:05:34 AM, 9/26/2023 10:37:55 AM falls between 9/14/2023 3:34:28 AM and 9/26/2023 10:37:55 AM.
IsImprovementStdDev: Marked as improvement because 56.93253291400037 (T) = (0 -192.78995183162735) / Math.Sqrt((205.51749312747626 / (299)) + (0.2561166740769467 / (3))) is greater than 1.9679030112610798 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (3) - 2, .975) and 0.20609076041504726 = (242.83626165179268 - 192.78995183162735) / 242.83626165179268 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
